METAL MATTRESE, FABRIC FOR BEDS;

Application filed December 19, 192 2 Serial l\l'o. 607,838.

To aZZ whmnz't may concern: t

Be it known that I, SOLOMON CAHAN, a citizen of the United States, residing in New York, in the county of New York and State of New York, have, invented certain new and useful Improvements in Metal Mattress Fabrics for Beds, of which the following is a specification.

The present invention relates to spring fabrics for reclining or sitting thereon such as beds, couches and the like, and one object of the inventionis to provide a spring fabric of links of dual wires, the fabric having resiliency throughout the entire plane thereof and being free from the tendency to form therein permanent depressions or imposed thereon is distributed over links composed of dual wires or strands, the links 'coacting to, yieldably' sustain the strain placed upon the fabric.

Another object is to provide a spring fabric comprising links composed of dual wires or strands, the links being connected laterally to each other by overlying and underlying engagement for forming the fabric and coacting with each other to yieldably sustain the weight imposed thereon.

Another object. is to provide a spring fabric comprising links, each: link consisting of an outer or enclosing wire or strand and an inner or enclosed wire or strand which conformably engages the outer wire or strand in the same plane andcoacts therewith to form the link.

I attain these and such other objects and advantages as may appear during the subjoined description by way of example of .oneembodiment of the invention, shownin the accompanying drawings in which Figure 1, is a plan view,.the spring fabric being broken transversely and longitudinally for convenience of illustration and indicating that it is composed in width andlength of a greater number of links than shown in said View. I g Figure 2, is a fragmentary plan view of the spring fabric shown in Fig. 1, provided with a modified form of marginal connec tion, the spring fabric being broken transversely. i 9

links 15 and helix connecting members 16.

. The end-pieces 10 and 11 have there- ;through the spaced holes 18. for receiving eyes 19 and at the'opposite end the hooks 20, the eyes :19 lying in one plane,as shown a horizontal plane,and the hooks 20 lying in a transverse plane, asshown a vertical plane. Each ofthe mid-links consists of dual Wires or strands bent into conforming engagement on the same plane whereby an v The spring fabric comprises in its main parts or elements the mid-links 14, marginal outer or enclosing link and an inner or enclosed link is formed, both of the outer and inner links lying on substantially the same plane, and constituting a link of dual Wires having the eye portion'19, and the hook ends 20 formed at the free ends of the dual wires, the hook ends 20 having four hooked portions. The opening of the eye 19 is of such size and curvature as to receive the quadruple hook portions of the hook ends 20 of another link and prevent movement of the hook ends in the eye, and maintain the dual wires composing the hookends 20 of the second link in the horizontal plane of these dual wires in the body of-such link. For operatively connecting laterally a mid-link 14 to an adjacent mid-link 14, the side of the first link at the Obr tuse portion of the diamond adjacent to the corresponding obtuse portion of a second mid-link is carried over and then under the second link, asshown in Fig. 8, whereby the midlinks cooperate for supporting each other, the dual wires or strands of one link bearing down upon and then upwardly upon the dual Wires or strands of the other link. For connecting the mid-links 14 to each other longitudinally, the hook end 20 of one link is engaged in the eye 19 of a second link as shown in Fig. 9, the eyes 19 of the mid-links preventing movement of the quadruple Wires or strands of. the hook ends 20 in the eyes, and maintaining the dual Wires or strands composing the hook ends in substantially the plane occupied by these wires in the bodies of the links.

For connecting the midlinks 14: to endpieces such as 10 and 11, the helix members 16 are provided. The helix members 16 have helix body portions having at one end a hook 21 with an indentationor pocket 22 formed thereon, and having at their other end a circular hook 23 For connecting the midlinks 11 to the en'dpieces 10 the eyes 19 of the mid-links are engaged in the indentations or pockets 22 of the helix members, these indentations or pockets preventing movement of the dual wires or strands of the eyes 19 of the mid-links out of the same plane, thecircular hooked ends 23 of the helix members being engaged'in the spaced holes 18 of the end-pieces 10. For connecting the mid-links .14 to the end-piece 11, the rings 21 are provided, having somewhat elongated openings 25 of a size and shape to receive the hook ends 20 of the mid-links, and serving to prevent movement of the hook ends and to maintain the wires or strands of the mid-links and of the hook ends 20 in the same plane, the circular hooks 23 of the helix members being engaged in the spaced holes 18of the end-piece 11.

The marginal links 15 are substantially one-half portions of the mid-links 14, the mid-links being cut longitudinally. The

marginal links 15 like the mid-links 14 are composed of dual wires or strands, and have eyes 26 and hooked ends 27 similar to the eyes 19 and hooked ends 20 of the mid-links, but have straight sides and two inclined sides connected by obtuse portions of the links. The marginal links 15 are connected to each other by engagement of the hooked ends 27 in the eyes 26 in manner similar to that before described for connecting the mid-links to each other, and are connected to the end-piece 10 by the eyes '26 engaging with the indented ends 21'of'helix members 16, the circular ends 23 whereof engage the spaced holes 18 of the end-piece 10, and are connected to the end-piece. 11 by the hooked ends 27 engaging in the rings 20 which are connected to the helix members 16 having their circular ends 23 engaging in the spaced holes 18 of the end-piece 11. The obtuse side portions of the marginal links 15 are connected to obtuse side portions of adjacent mid-links 14 by the same manner of overlying and underlying engagement as before described for connecting the mid-links 11 to each other laterally or at their sides.

It will be noted that the marginal links 15 constitute means for supporting the midlinks 11 in the longitudinal line of the spring fabric at the margins of the midportion of the spring fabric formed by the mid-links.

Instead of the marginal links 15 marginal plates 28, Fig. 2, may be used. The marginal plates 28 extend longitudinally of the spring fabric, being connected at respective ends to the end-pieces 10 and 11 by helix members 16 engaging in the holes 18 in the end-pieces. The marginal plates are pro vided with longitudinally alined openings, such as 29 and 30, there-through near their inner edges, these edges being rolled or channeled and provided with substantially circumflex raised and depressed portions 31 and 32, shown in Fig. 7, for receiving the wires or strands of the mid-links 14, the obtuse portions of adjacent mid-links being received in the openings 29 and30 in overlying and underlying engagement for supmodifications thereof and variations therein without departing from the spirit of the invention'or exceedingthe scope of the appended claims.
